- •
Results showed that the new tools in PMF 5.0 are very useful in the case of small datasets
- •
The application of the appropriate constraints may be needed to reduce the rotational ambiguity of the solution for small datasets
- •
The case of biomass burning revealed that sources with high seasonal variability are vulnerable to resampling techniques in small datasets
- •
Biomass burning (11%), shipping (10%), sea salt (9%), sulfates (34%), mineral dust (2%) and vehicle emissions (34%)
